PENNSYLVANIA, ASSIGNOR OF ONE- FOURTH TO FRANK J. RICHARDS, OF SAMEPLACE.

CABLE-GROSSINe.

SPECIFICATION forming part of Letters Patent No. 460,912, dated October6, 1891.

Application led May 8, 1891.

To ctZZ whont it may concern:

Beit known that I, JOSEPH DuNoTT, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsyl-Vania, have invented a new and useful Improvement in Oable- Orossin gs,which improvement is fully set forth in the following specification andaccompanying drawings.

My invention relates to improvements in cable-crossings, and has for itsobject mechanism whereby a cable car can be carried around a curvedportion of a track when released from the main cable or carried acrossthe crossing of two cables; and for these purposes it consists, first,of a series of jointed or connected blocks adapted to move in a curveand provided with means for contacting with the grip-arm.

It further consists of the combination of parts, substantially ashereinafter described.

Figure l represents a plan view of a conduit-track with cross anddiverging branches, the roadway and top of said conduit being removed toshow the arrangement thereof, and a switch and carriage, with operativemechanism therefor embodying my invention. Figs. 2 and 3 represent,respectively, views of the switch in different positions. Fig.trepresents an end view of the switch, with sectional view of theconduit. Fig. 5 represents a horizontal section, on an enlarged scale,ot' a portion of the carriage. Fig. 6 represents a horizontal sectionofthe carriage, the springarxn being depressed. Fig. 7 represents a topView of a carriage-block, the spring-arm being shown as engaging thegrip-arm. Fig. 8 represents a side view, on an enlarged scale, of aportion of the device. Fig. 9 represents a section on line x ne, Fig. S.Fig. lO represents a perspective View, on a reduced scale, f the blockcontaining the spring-arm which coutacts with the grip-arm.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a conduit having the divergingbranches B and O, with curved connecting portions, and the cross-conduitD, connected therewith.

Movable on the tracks or guides E, which are secured in said conduits,is a carriage F,

Serial No. 392,004. (No model.)

formed of a number of short blocks or trucks linked together at theirends, so as to be adapted to easily move by means of the roller G alongthe curved portions of the said tracks. Connected with pins or studs Hon one side of a block of the said carriage F are the ends of a cord orchain .I ,y which latter passes around the rollers K, L, M, and N, and adrum NX, being wound around the latter a number of times to prevent itsslipping therefrom. The direction of the rotation of the drum N Xdetermines the direction of movement of the cord J, and consequently ofthe carriage F. Any suitable motor or means may be employed for rotatingthe drum NX.

To guide the carriage F in its movements, so that it will travel on theproper track, a switch P is provided, said switch having three tracksthereon Q Q Q2, corresponding to the tracks E of the main conduit andbranches, respectively. To move the switch laterally on its supports P,and thereby adjust the same, it is connected by two bars R with therotary toothed wheels S, which mesh with racks T on a sliding bar U. Thebar U is operated by means of a gear-wheel V, which meshes with a rackXV on said bar U and a rack X on a sliding bar Y.

One of the blocks F of the carriage is provided with a pivoted arm A',one end of which is normally held or projected outward from the side ofthe block by means of a spring B', so that the inclined face BX of thelower end of the grip may ride on the same, pressing it within theblock, and thus passing over it, whereby the said arm may engage andbear against the grip-arm when the carriage is moved in the direction ofthe same.

The carriage is of such length and theparts are so arranged that whenthe said carriage is returned to the track in the main conduit the blockcontaining the spring-controlled arm has passed over and is a shortdistance from the switch, which is then adjusted for the proper track.The grip-arm, after riding over the spring-arm A', is released from themain cable, and motion is imparted to the drum N X, so as to move thecarriage, bringing the end of the arm A against the grip-ar1n, so as totorce the latter, with the attached car, around the curve, after whichthe motion of the drum is reversed, so that the carriage is returned tothe track E in the main conduit A, Where it is in readiness for anothercar.

In the cross-conduit D a carriage F is employed, similar in character tothe carriage F in the conduit A, and the carriages are of such lengththat When not in operation they are out of the way of each other, sothat there need not be any depression of either track. The carriage F isoperated by means similar to those operating the carriage F.

In the vicinity of the drum N is an alarm- C in an electric circuit D',and which is operated in any ordinary manner, so as to notify theoperator at the drum of the time for rotating the same.

It will be seen that by constructing the carriage of short blocks ortrucks linked together the same can easily be made of a proper length tosuit any curve vor crossing.

Having thus described my invention, what I claim as new, and desire vtosecure by Letters Patent, is-

1. A conduit With a diverging branch, tracks in said conduit and branch,a carriage consisting of linked blocks guided on said tracks, cordsconnected with said carriage, and mechanism for operating saidcords,.said

parts being combined substantially as described. Y

2. A conduit having a divergng branch, tracks in said conduit andbranch, a switch With tracks connecting sections of said tracks, and alinked carriage movable on said tracks and having a spring-arm adaptedto contact with a grip-arm, said parts being combined Y substantially asdescribed.

3. A main track havinga diverging branch, a switch With tracks thereonadapted to connect sections of said main track and diverging branch,mechanism for laterally moving said switch, linked blocks movablein'said tracks, a spring-arm projecting from one of said blocks andadapted to be engaged by a grip-arm, and mechanism for operating saidblocks, said part-s being combined substantially as described.

4. In a cable-crossing, a carriage consisting of linked blocks, one ofwhich has a pivoted spring-arm, a track, and a griparm with an inclinedface on the side of its lower end, said parts being combinedsubstantially as described.
